Abstract
Patente de Invenção:<B>"DISPOSITIVO DE DIREçãO"<D>. Um dispositivo de direção para a direção das rodas de um eixo de direção executado como eixo de arraste ou de avanço de um veículo automotor apresentando ao menos três eixos, com uma disposição hidráulica, que apresenta um agregado de ajuste para ativação de direção das rodas, uma válvula de regulagem/controle para ativação com pressão de conexões hidráulica do agregado ajuste bem como uma válvula de liberação, com que o dispositivo de direção é comutável entre uma operação normal e uma operação de emergência, sendo que na última as conexões hidráulicas do agregado de ajuste ficam unidas entre si, deve ser aperfeiçoado no sentido de que a segurança do veículo seja aumentada. Esse problema é solucionado, de acordo com a invenção, pelo fato de que estão previstos quatro elementos de estrangulamento, dos quais o primeiro está disposto antes e o segundo depois de um ponto de conexão da válvula de liberação a um primeiro conduto hidráulico unindo válvula de regulagem/controle e agregado de ajuste, e dos quais o terceiro está disposto antes e o quarto depois de um ponto de conexão da válvula de liberação a um segundo conduto hidráulico unindo válvula de regulagem/controle e agregado de ajuste.Invention Patent: <B> "STEERING DEVICE" <D>. A steering device for steering the wheels of a steering axle made as a driving or driving axle of a motor vehicle with at least three axles, with a hydraulic arrangement, which presents an adjustment aggregate for activating the steering of the wheels, a regulating / control valve for activation with pressure of the hydraulic connections of the adjustment unit as well as a release valve, with which the steering device can be switched between a normal operation and an emergency operation, the latter being the hydraulic connections of the aggregate settings are linked together, it must be improved in the sense that the safety of the vehicle is increased. This problem is solved, according to the invention, by the fact that four choke elements are provided, of which the first is disposed before and the second after a connection point of the release valve to a first hydraulic line connecting the regulation / control and adjustment unit, and of which the third is disposed before and the fourth after a connection point of the release valve to a second hydraulic line connecting regulating / control valve and adjustment unit.
